Late posterior hip instability after lumbar spinopelvic fusion
The kinematic relationship between the hip and the axial skeleton is dynamic and can be variable based on individual anatomy. It has been shown [1] that pelvic incidence (sacral slope + pelvic tilt) can be used as a proxy to determine the ability of the pelvis to accommodate changes in sagittal balance. Individuals have varied pelvic incidence and thus may adapt differently degenerative and/or ...
متن کاملLate instability following total hip arthroplasty.
Instability is one of the most common complications after total hip arthroplasty and can present early or late after hip replacement. Late instability is considered if the event occurs five or more years after the primary arthroplasty, and in contrast to early dislocation, it appears to require operative intervention. The incidence of late instability may be greater than initially appreciated, ...
متن کاملEvaluation and management of chronic total hip instability.
Given the increasing number of total hip arthroplasty procedures being performed annually, it is imperative that orthopaedic surgeons understand factors responsible for instability. In order to treat this potentially complex problem, we recommend correctly classifying the type of instability present based on component position, abductor function, impingement, and polyethylene wear. Correct clas...
متن کاملManagement of instability and osteolysis after total hip arthroplasty.
William J. Hozack, MD: The radiographs demonstrate a dislocated total hip arthroplasty (THA) with extensive bone lysis on both the acetabular and femoral sides. Component fixation appears intact. Closed reduction is indicated in this case, as in virtually all cases of dislocation. A dislocated THA is painful for the patient and requires immediate attention. Furthermore, there are many instances...
متن کاملEffects of Spinopelvic Balance on Acetabular Version in Total Hip Arthroplasty
The orientation of acetabular component is influenced by pelvic tilt, body position and individual variation in pelvic parameters. Most adverse events attribute to improper positioning of the acetabular component in the functional position. There is evidence that the orientation of the pelvis changes from the supine to standing position, consequently changing the orientation of acetabular cup v...
